refactor: rename remaining tests to NATS.Server.Core.Tests

- Rename tests/NATS.Server.Tests -> tests/NATS.Server.Core.Tests - Update solution file, InternalsVisibleTo, and csproj references - Remove JETSTREAM_INTEGRATION_MATRIX and NATS.NKeys from csproj (moved to JetStream.Tests and Auth.Tests) - Update all namespaces from NATS.Server.Tests.* to NATS.Server.Core.Tests.* - Replace private GetFreePort/ReadUntilAsync helpers with TestUtilities calls - Fix stale namespace in Transport.Tests/NetworkingGoParityTests.cs
